NeoForge API (1.20.1 → 1.21.8) – A Modern Successor to Forge

Forge has been the backbone of Minecraft modding for over a decade. Nearly every big content mod from Thaumcraft to Thermal Expansion was built on Forge. But as Minecraft grew, so did frustrations. Forge updates lagged behind new Minecraft releases, compatibility issues piled up, and community trust in the project’s leadership weakened.

Out of that tension came NeoForge: a fork created by former Forge developers who wanted a cleaner, more responsive alternative. Unlike Fabric which aimed to be lightweight and experimental NeoForge kept Forge’s mission: supporting large, complex mods. But it also tried to modernize the development process.

My Experience: Testing Forge vs NeoForge

I built a test pack with about 80 mods (including optimization staples like Embeddium, FerriteCore, and Lithium ports) and ran it on both Forge and NeoForge:

• Load Times: NeoForge did feel faster in my case menus loaded in under 40 seconds versus closer to a minute on Forge. But results varied when I swapped mods; some Forge-only libraries slowed NeoForge down.
• Compatibility: Forge still had broader mod support, especially for older mods written pre-1.20. NeoForge handled most new mods fine, but a few threw errors.
• Stability: Both platforms crashed occasionally with large packs. NeoForge gave cleaner debug logs, which made troubleshooting easier, while Forge often buried the cause.

So while NeoForge felt smoother day-to-day, Forge remained the “safer bet” for older packs.

Community Feedback – Split but Growing

Looking through Reddit threads (r/FeedTheBeast, r/MinecraftModding), the discussion is rarely one-sided:

• Pro-NeoForge voices:
  “Most major devs have already moved to NeoForge. It feels cleaner, loads mods faster, and doesn’t fight with optimization tools.”
• Pro-Forge voices:
  “Forge is still more stable for me. On 1.20.1, I had fewer crashes sticking with Forge compared to NeoForge.”
• Middle ground:
  “NeoForge and Forge are mostly interchangeable on 1.20.1, but future versions may diverge. If you want the newest mods, NeoForge is probably better. If you want guaranteed compatibility, Forge is safer.”

Some also noted bridges like SinYtra Connector (to run Fabric mods on Forge/NeoForge) and Embeddium (a Sodium fork) as tools that ease the transition.

FAQs

Q: Does NeoForge replace Forge?
No. Forge still exists and is widely used. But many modern mods (post-1.20) are moving to NeoForge.

Q: Can I run Forge mods on NeoForge?
Yes, in most cases. On 1.20.1, Forge and NeoForge are highly interchangeable. But older mods may need Forge.

Q: Which is faster?
Some players report NeoForge loads packs faster and crashes less, but there isn’t a fixed number (like 20%). Results vary by setup.

Q: Should I switch?
If you’re building a modern modpack (1.20+), NeoForge is worth trying. If you rely on legacy mods, Forge is still the safer option.

Final Thoughts

NeoForge isn’t a “replacement” for Forge so much as a continuation with a new philosophy. It inherits Forge’s strengths support for massive, complex mods but aims to solve the performance and update lag issues that dogged its predecessor.

For me, NeoForge felt faster and easier to debug, but Forge still had the wider safety net of mod compatibility. The community itself reflects this split: some see NeoForge as the future, others stick with Forge for stability.

The truth is simple: neither is “better” in every case. But if you’re starting fresh with Minecraft 1.20 or later, NeoForge may give you the smoother experience while Forge remains the backbone for older mods and legacy packs.
